Dave - thank you for sharing. It is nice to see the guideline for your DMs and I can personally confirm this is what was practiced on our recent Coz trip. We dove all week with Julio (one night dive with Pepe) and during this week, the currents were crazy. Our safety was the utmost importance followed by the diver experience. On our first dive, my dive buddy ran into issues 10 minutes into the dive and was beginning to panic and wanted to ascend. I started pulling her down so she wouldn't flight to surface and Julio immediately picked up on the issues, assisted to the sand, and began to calm her down. We were soon back on our way to continue the dive and completed the rest of the week without incident.
